Hanle Effect in Transport through Quantum Dots Coupled to Ferromagnetic Leads

Matthias Braun, Jürgen König, Jan Martinek

We suggest a series of transport experiments on spin precession in quantum dots coupled to one or two ferromagnetic leads. Dot spin states are created by spin injection and analyze…

Re-parameterization Invariance in Fractional Flux Periodicity

Shuichi Murakami, Ken-ichi Sasaki, Riichiro Saito

We analyze a common feature of a nontrivial fractional flux periodicity in two-dimensional systems. We demonstrate that an addition of fractional flux can be absorbed into re-param…

Kinematics of Persistent Currents in Nanotubes and Tori -Time-reversal symmetric gauge field and its application-

K. Sasaki, Y. Kawazoe

The basic properties of conducting electrons in carbon nanotubes are reviewed from a theoretical perspective, and studies performed on persistent currents in toroidal carbon nanotu…

Fractional Flux Periodicity in Doped Carbon Nanotubes

K. Sasaki, S. Murakami, R. Saito

An anomalous magnetic flux periodicity of the ground state is predicted in two-dimensional cylindrical surface composed of square and honeycomb lattice. The ground state and persis…

Modulation of Noise in Submicron GaAs/AlGaAs Hall Devices by Gating

Yongqing Li, Cong Ren, Peng Xiong +3

We present a systematic characterization of fluctuations in submicron Hall devices based on GaAs/AlGaAs two-dimensional electron gas heterostructures at temperatures between 1.5 K…

Nambu-Goldstone Mode in a Rotating Dilute Bose-Einstein Condensate

Masahito Ueda, Tatsuya Nakajima

The Nambu-Goldstone mode, associated with vortex nucleation in a harmonically confined, two-dimensional dilute Bose-Einstein condensate, is identified with the lowest-lying envelop…
